What is the magnitude response of a filter?
The magnitude response of filters can be characterized in terms of the frequency bands the filter will pass or reject. In Fig. 4.9 the ideal magnitude responses of the four most frequently used filter types are illustrated as a function of ω in radians per second.
What is the formula for magnitude response?
A transfer function, H(ω), has a magnitude response |H(ω)| and a phase response ϕ(ω) such that H(ω) = |H(ω)| eiϕ(ω). The only difference between a complex number z and a transfer function H(ω) is z is one complex number whereas H(ω) is an entire function of complex numbers: a complex number for each frequency value ω.
What is the magnitude of response?
In most cases, the magnitude response is the ratio of the amplitude of frequencies in the output signal to the amplitude of frequencies of the input signal. Usually, if we want to describe how a system impacts the amplitudes of frequencies in a signal, we will use the term magnitude response.
What is the frequency response of FIR filter?
Since all signals can be decomposed into sinusoidal components, the frequency response function characterizes frequency regions called stop bands and pass bands, where the FIR filter will reject signal components or pass them nearly undistorted.
